D/C from ranked with internet connection

I was about 9 minutes into a ranked game and doing fairly well (2/0/1) and I randomly D/Ced. I tried reconnecting but I was stuck in base unable to type, buy, or move. I tried restarting the client 3 times each time I ended up stuck in base unable to act. Tested my connection and it was fine. Why did this happen? Can I be forgiven for this ranked leave? I'm already in ELO hell and it was looking pretty good for us this game.

connection test taken while this was happening.
